Application filed October 16, 1907. Sei-1.31 No. 397,637.

To all whom it may concern.

Be it known that we, HARRY J. Klei-1R and WiLLiAM A. HOHMAN, citizens ofthe United States of America, residing at Bellinghani, in the county ofWhatcom and State of tVashington, liave'invented certain new and usefulImprovements in Saw-Guides, of which the following is a specification.

This invention relates to new and useful improvements in wood sawing andhas relation more particularly to a saw holder to be employed withundercut saws. A

In the event of a log lying up on two e1evated places at each end of thelog it is impossib e to saw the log from the top or that portion whichis sprung down as the log would close.upon the saw during the cuttingoperation, but when the sprung portion is cut from beneath the weight ofthe log will open the eut made by the saw and thereby assist in theoperation.

It is an obj ect of the invention to provide a novel carriage to beemployed in sawing a log from the under side.

It is a further object of the invention to provide in a device of thischaracter novel means whereby the cross cut saw will be held inengagement with a log.

It is also an object of the invention to provide in combination with adevice of this kind, novel means whereby the carriage may be held inoperative osition. i

Furthermore, an o ject of the invention is to roducc a device of thecharacter noted, which will possess advantages in points of sim ilicity,efliciency and durability, proving at t e saine time comparativelyinexpensive to manufacture. Y

iVith the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangementand combination ofpart-s to be hereinafter more fully set forth and claimen In describingthe invention in detail, reference will be had to the accompanyingdrawings forming part of this specification wherein like charactersdenote corresponding parts in the several views, in which- Figure 1, isa view in side elevation illustrating the invention in applied position.Fig. 2, is aview in front elevation of the dcvice with parts omitted.Fig. 3, is a view in detail of a shaft -employed in the invention.

'Y In the drawings, 1 denotes the base of a.

steel frame approximatelyv U-shapcd in form.

Said frame has 'llat metal stems 2, bent adjacent the base m such manneras to cause the edges of the same to aline.

Extending centrally through the base 1, of

the frame is an upright 3, terminating at itsupper end in a for i et, inwhich is fixed a shaft 5. This shaft 5, projects beyond both sidesof thefork 4, and has its ends bifurcated as at 6. This bifurcated portion ofthe shaft 5 straddles the inner edges of the stems 2, and thereby holdsthe upright 3, against any undue lateral movement with relation to thebase as will, it is thought, be fully understood. The fork 4, forms withthe upright 3 a shoulder 7, against which bears a spira spring S, whichalso cont-acts with the base 1, of the frame. By means of this spring,an upward pressure is constantly exerted against the shoulder of thefork.

Loosely mounted on the shaft 5, is a. grooved wheel 9, and in one of thegrooves of the wheel is adapted to rest the back of a cross cut saw 10.This wheel will readily permit the rcciprocation of the saw and as it Acuts its way in the log, the spring 8, will constantly press the sawupwardly and hold the teeth of the saw in contact with the log.

The uprightI 3, is provided in its lower end with a croc` pin 11, whichis adapted to contact with a washer 12, embracing the upright. Thiscross pin 11, limits the upward movement of the upright.'

Adjacent to the upper end of one of the stems 2, is a perforation 13,through-which passes an end of a securing member 14, which. 1s suitablycoiled as at 15, to hohl the same against displacement. The end of thisin enibcr 14, terminates in an inwardly inclined pointed prong 16, whichis forced into the log to be operated upon and forms a spring anchoringineans'for the upper portion of the frame.

Secured` to the under side ofthe base 1, is, a cross piece 17, whichprojects beyond the ends of the base and is coiled to form bearings lS,for the approximately V-sliaped fork 19, which terminates in points '20,which engage the ing to be operated upon and form a securing medium forthe lower portion of the i The fact that the fork 19, is approximatelyV-shapcd prevents any undue movement of the carriage during the courseof the operation. T o prevent any outward movement of the carriage eachmember of the fork is provided with a sleeve 21, which is intended toabut a bearing 18. The sleevespZi, are connected by a cross bar 24, andsaid cross bar is engaged by the hooks 25, of the arms '26, which aresecured to the'A base of the frame b v the securing bolts 23. rThe fork19, is slidal'le loosely through the bearings 18, and the sleeves 21.This permits of a ready adjnstmentof the lower portion'of lthe carriage`with relation to the log to be operated upon- When the desiredadjustment has been attained the fork is held against movement by theset screws 22.

The cross piece 1T, may be secured to the base 1, of the machine in anysuitable or desired manner and ss shown in the drawing bolts 23, areemployed for 'the purpose.

lVhat we claim is:

1. In a saw guide, a U-shaped` frame, an upright movable through thebase of the frame, a shaft carried by the upright projecting therebeyondand engaging the sides of the frame, ya roller loosely mounted on theshaft, means for moving the upright longitudinally and anchoring meansfor the frame.

v2. In asaW guide, a U-shaped frame, an upright movable through the baseof the frame, a shaft carried by the upright projecting therebeyoml andengaging the sides of the frame, a rollerkloosely mounted on the shaft,a spring contacting with the frame `and the upright for impartinglongitudinal movement to the upright and anchoring means for the frame.

3. In a saw guide, a U-shaped frame, an upright movable through the baseof the frame, a shaftcarried by the upright, said shaft having its endsbifurcated and embracing the sides of the frame, a roller looselymounted on the shaft, means for imparting movement to the shaftlongitudinally of the sides of the fra-me and anchoring means for theframe.

4. In a saw guide, a frame, a supporting roller carried by the frame, ananchoring means carried by one end of the frame, bearings carried by theopposite end of the frame, and an anchoring fork slidable within thebearings.

In a saw guide, a frame, a supporting roller carried by the frame, ananchoring means carried b v one end of the frame,-bear ings, and meansfor holding the fork against movement through the -bearings.

6. In a saw guide, a frame, a supporting roller carried by the frame, ananchoring means carried by one end of the frame, bearings carried bythe. opposite end of the frame, an anchoring fork slidable within thebear'- ings, sleeves embracing the fork, means for holding the sleevesagainst moif'efncnt with relation to the frame, and means carried by thesleeves for holding the fork against movement.

7 In a saw guide, a frame, a supporting roller carried by the frame, ananchoring means carried by one end of the frame, bearings carried by theopposite end of the frame, an anchoring forlt slidable within thebearings, sleeves embracing the fork, and means on the frame for holdingthe sleeves against movement with relation to the frame and meanscarried by the sleeves for holding the fork against movement. I

8. In a saw guide, a frame, a supporting roller carried by the frame,an. anchoring means carried by one end of the frame, bearings carried bythe opposite end of the frame, an anchoring fork slidable within thebearings, sleeves embracing the fork, a bar connecting the sleeve, armscarried by the frame engaging the bar and' means carried by the sleevefor holding the fork against movement.

9. In a saw guide, a frame approximately U-shaped an upright movablethrough the base of the frame, a fork on the upright, a spring embracingthe upright bearing against the base of the frame and the base of thefork, a shaft carried by the fork operative therebeyond on bot-hsidesand engaging the frame, a pulley loosely mounted on the shaft within thefork, and anchoring means carried by the frame.
